The problem: you want to do serious scalability testing (1000s of VMs)
of your management stack. If each guest eats up a few 100MiB and
competes for CPU, that requires a serious host machine. Which you don't
have. You also don't want to modify the management stack at all, if you
can help it.

Hi,
This patch series is a revised version of Kemari for KVM, which
applied comments for the previous post. The current code is based on
qemu.git d03d11260ee2d55579e8b76116e35ccdf5031833.
The changes from v0.2.5 -> v0.2.6 are:
- use qemu_{put,get}_be32() to save/load niov in event-tap

Introduce migrate_ft_trans_put_ready() which kicks the FT transaction
cycle. When ft_mode is on, migrate_fd_put_ready() would open
ft_trans_file and turn on event_tap. To end or cancel FT transaction,
ft_mode and event_tap is turned off. migrate_ft_trans_get_ready() is
called to receive ack from
